Layer-by-Layer (LbL) Assembly, A "Gentle Yet Flexible" Method Toward Functional Biomaterials

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.

Polyelectrolyte Multilayer Films and Membrane Functionalization

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.

Questions

1–6 of 6 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  3. What causes the difference between the yellow and amber colors of this product?

    1 answer

    1. The quality specification for this item is only a residue on evaporation and appearance (color and form) assay for this technical grade product. Differences in color could be from numerous causes such as overall polymer composition, color perception, or appearance of raw material. It is not uncommon for the poly(styrenesulfonic acid sodium salt) to have color variations.

  4. Hello, Just to confirm does the concentration of PVS vary from 30-40% in this raw material? Does 'Residue on evaporation' refer to the concentration of just PVS and not any impurities also in the raw material? I need to know the concentration of PVS.

    1 answer

    1. Residue on evaporation refers to any solid material remaining after evaporating the water away. This value does not take into account potential impurities present in addition to the Poly(vinylsulfonic acid, sodium salt). Therefore, the concentration may vary slightly from the value provided on the lot-specific Certificate of Analysis.

  6. What is the average molecular weight of the SIgma Poly(vinylsulfonic acid, sodium salt)?

    1 answer

    1. The molecular weight between 2000 and 5000 g/mol.
